I'm about to do an almost stock rebuild on a 2006 LQ4 engine.

I'm upgrading to LQ9 pistons and Summit Stage 1 truck camshaft.

I don't see any reason to use more than stock TTY head bolts but the GM ones seem to be a bit costly compared to others, even Trick Flow offers a set.

Should I be concerned that everything is knock-off cheap import stuff except actual GM bolts?

For head bolts, I would NOT have much faith in Chinesium headbolts. Just don't buy from Fleabay or Amazon.....

Felpro, Enginetech, Mahle, Summit brand are cheaper options. I have used the Summit brand and Felpro TTY bolts with no issues.
